Description
Die Erfindung betrifft eine hydraulisch spannbare Vorrich tung zum Verbinden eines zylindrischen Nabenkörpers mit einer Welle, im wesentlichen gebildet aus einem den Naben körper umgebenden Druckring mit einer Außenkonusfläche, einem Spannring mit einer an die Außenkonusfläche des Druckringes angepaßten Innenkonusfläche sowie einem am verjüngten Ende des Druckringes gehaltenen Stützring, dessen äußere Umfangsfläche von einem den Spannring fortsetzenden Bund umschlossen ist, wobei der Druckring und der Spannring mit Hilfe einer in einen Druckraum einleitbaren Druckflüs sigkeit gegeneinander verspannbar und durch Schrauben in ihrer Spannposition gesichert bzw. aus dieser Position abdrückbar sind.The invention relates to a hydraulically tensionable Vorrich device for connecting a cylindrical hub body with a shaft, essentially formed from one of the hubs pressure ring surrounding the body with an outer cone surface, a clamping ring with one on the outer conical surface of the Pressure ring adapted inner cone surface and a tapered end of the pressure ring held support ring, the outer peripheral surface of a continuation of the clamping ring Bund is enclosed, with the pressure ring and the tension ring with the help of a pressure flow that can be introduced into a pressure chamber liquid can be braced against each other and screwed in secured their clamping position or from this position are pushable.
Durch die DE-PS 34 01 837, insbesondere Fig. 1, ist eine Vorrichtung mit den zuvor genannten Merkmalen bekannt.From DE-PS 34 01 837, in particular Fig. 1, a device with the aforementioned features is known.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der gattungsgemäßen Art auf möglichst einfache Weisein bezug auf ihre Handhabung, vor allem hinsichtlich einer leichten Zugänglichkeit zum Druckraum und einer zuverläs sigen Lösbarkeit der Verbindung zu verbessern.The invention has for its object a device of the generic type in the simplest possible way with regard to their handling, especially with regard to one easy access to the pressure chamber and one reliable improve the releasability of the connection.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß am Bund des Spannringes ein Flansch lösbar angebracht ist, der Durchgangsbohrungen für in Gewindebohrungen des Stützringes eindrehbare Sicherungsschrauben sowie Gewindebohrungen für gegen die plane Stirnfläche des Stützringes abstützbare Abdrückschrauben aufweist.This object is achieved in that on The flange of the clamping ring is releasably attached to the Through holes for threaded holes in the support ring screwable locking screws and threaded holes for can be supported against the flat end face of the support ring Has jack screws.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigenAn embodiment of the invention is in the drawing shown and is described in more detail below. It demonstrate
Fig. 1 eine Vorderansicht auf einen Teilbereich einer Spannverbindung, Fig. 1 is a front view of a portion of a clamping connection,
Fig. 2 den Schnitt nach der Linie II-II in Fig. 1, Fig. 2 shows the section along the line II-II in Fig. 1,
Fig. 3 den Schnitt nach der Linie III-III in Fig. 1. Fig. 3 shows the section according to the line III-III in FIG. 1.
Ein zylindrischer Nabenkörper 1 soll derart mit einer Welle 2 verbunden werden, daß insbesondere Drehmomente und Axial kräfte übertragbar sind. Die dazu vorgesehene Spannvorrich tung besteht im wesentlichen aus einem Druckring 3, einem Spannring 4, einem Stützring 5 sowie einem Flansch 9.A cylindrical hub body 1 is to be connected to a shaft 2 in such a way that, in particular, torques and axial forces can be transmitted. The provided Spannvorrich device consists essentially of a pressure ring 3 , a clamping ring 4 , a support ring 5 and a flange 9th
Der den Nabenkörper 1 umgebende Druckring 3 wirkt über eine Außenkonusfläche 3a mit einer Innenkonusfläche 4a des Spannringes 4 zusammen. Am verjüngten Ende des Druckringes 3 ist der Stützring 5 aufgeschraubt, dessen äußere Umfangs fläche 5c von der inneren Umfangsfläche 4d eines den Spann ring 4 fortsetzenden Bundes 4b umschlossen wird. Der Stütz ring 5 enthält einen Kanal 5e für das Einleiten von Druck flüssigkeit in einen Druckraum 6, der über Dichtungen 12 abgeschlossen ist. Bei entsprechendem hydraulischen Druck gleitet der Spannring 4 auf der Außenkonusfläche 3a des Druckringes 3 (in Ebene der Fig. 2 nach rechts), wodurch die zum Verbinden des Nabenkörpers 1 mit der Welle 2 erforder lichen Radialkräfte erzeugt werden.The pressure ring 3 surrounding the hub body 1 interacts via an outer cone surface 3 a with an inner cone surface 4 a of the clamping ring 4 . At the tapered end of the pressure ring 3 , the support ring 5 is screwed on, the outer circumferential surface 5 c of the inner circumferential surface 4 d of a clamping ring 4 continuing collar 4 b is enclosed. The support ring 5 contains a channel 5 e for the introduction of pressure liquid in a pressure chamber 6 , which is completed via seals 12 . With appropriate hydraulic pressure, the clamping ring 4 slides on the outer conical surface 3 a of the pressure ring 3 (in the plane of FIG. 2 to the right), whereby the radial forces required to connect the hub body 1 to the shaft 2 are generated.
Die zwischen den Umfangsflächen 4d und 5c angeordnete Dichtung 12 ist derart gestaltet, daß die beim Verspannen auftretende elastische Aufweitung des Spannringes 4 und dessen Bundes 4b federnd kompensiert wird. Um die vorgenannten Flächen 4d und 5c sowie die Dichtung 12 gegen über Schmutz und Feuchtigkeit abzuschirmen, befindet sich ein Abstreifring 11 zwischen einem ringförmigen Ansatz 5d des Stützringes 5 und der inneren Umfangsfläche des Flansches 9.The between the circumferential surfaces 4 d and 5 c arranged seal 12 is designed such that the elastic expansion of the clamping ring 4 and its collar 4 b occurring during tensioning is compensated for in a resilient manner. In order to shield the aforementioned surfaces 4 d and 5 c and the seal 12 against dirt and moisture, there is a scraper ring 11 between an annular shoulder 5 d of the support ring 5 and the inner peripheral surface of the flange 9 .
Zum Halten der Verbindung in ihrer gespannten Position ist am Bund 4b des Spannringes 4 der Flansch 9 angebracht, der Durchgangsbohrungen 9a für Sicherungsschrauben 7 aufweist. Diese Schrauben 7 greifen in Gewindebohrungen 5a innerhalb des Stützringes 5 ein. Die Schrauben 7 werden lediglich handfest angezogen; ein Drehmomentschlüssel ist dazu nicht erforderlich.To hold the connection in its tensioned position, the flange 9 is attached to the collar 4 b of the clamping ring 4 and has through holes 9 a for locking screws 7 . These screws 7 engage in threaded holes 5 a within the support ring 5 . The screws 7 are only hand-tightened; a torque wrench is not required.
Zwischen den Durchgangsbohrungen 9a des Flansches 9 sind Gewindebohrungen 9b angeordnet, in die Abdrückschrauben 8 zum Lösen der Verbindung aus der gespannten Position einge dreht werden können. Wie aus Fig. 3 ersichtlich, wirken dabei die Abdrückschrauben 8 gegen die plane Stirnfläche 5b des Stützringes 5. Als Abdrückschrauben 8 sind auch die Spannschrauben 7 verwendbar. Vor dem Betätigen der Abdrück schrauben 8 empfiehlt es sich, die Verbindung mittels der Druckflüssigkeit noch stärker zu verspannen, um die Haft reibung zwischen den Konusflächen 3a und 4a zu überwinden.Between the through bores 9 a of the flange 9 , threaded bores 9 b are arranged, into which jack screws 8 can be turned to release the connection from the tensioned position. As can be seen from FIG. 3, the jacking screws 8 act against the flat end face 5 b of the support ring 5 . The clamping screws 7 can also be used as forcing screws 8 . Before actuating the trigger screw 8 , it is recommended to tighten the connection by means of the hydraulic fluid even more to overcome the adhesive friction between the conical surfaces 3 a and 4 a.
Wenn der durch Halteschrauben 10 lösbar mit dem Bund 4b des Spannringes 4 verbundene Flansch 9 entfernt wird, ist der Stützring 5 frei zugänglich. Er ist dann durch einfaches Drehen vom Druckring 3 abschraubbar, um beispielsweise die Dichtungen 12 auszuwechseln. Das Wiederanbringen des Flansches 9 wird durch einen am Bund 4b des Spannringes 4 vorgesehenen Zentrierbund 4c erleichtert.If the flange 9 detachably connected to the collar 4 b of the clamping ring 4 by the retaining screws 10 is removed, the support ring 5 is freely accessible. It can then be unscrewed from the pressure ring 3 by simply rotating it, for example to replace the seals 12 . The reinstallation of the flange 9 is facilitated by a centering collar 4 c provided on the collar 4 b of the clamping ring 4 .
